DS90CF363BMT/NOPB .

The DS90CF363BMT/NOPB is a programmable LVDS Transmitter converts 21 bits of CMOS/TTL data into three LVDS (low voltage differential signalling) data streams. A phase-locked transmit clock is transmitted in parallel with the data streams over a fourth LVDS link. Every cycle of the transmit clock 21 bits of input data are sampled and transmitted. At a transmit clock frequency of 65MHz, 18 bits of RGB data and 3 bits of LCD timing and control data (FPLINE, FPFRAME, DRDY) are transmitted at a rate of 455Mbps per LVDS data channel. Using a 65MHz clock, the data throughput is 170Mbps. The DS90CF363B is fixed as a Falling edge strobe transmitter and will interoperate with a falling edge strobe receiver (DS90CF366) without any translation logic. This chipset is an ideal means to solve EMI and cable size problems associated with wide, high speed TTL interfaces.

• No special start-up sequence required between clock/data and /PD pins
